We report the synthesis and Zn sensing of a novel coumarin-hydrazine conjugate 3-{1-[(4, 6-Dimethyl-pyrimidin-2-yl)-hydrazono]-ethyl}-chromen-2-one (3). Compound 3 can act as a neat fluorescent Zn sensor by an increment in fluorescence intensity along with an appreciable red shift. Fluorescence enhancement is caused by complexation through cis-trans isomerization process in the presence of Zn ion. The practical utility of 3 was demonstrated by successful test kit experiment to detect Zn in water under UV-light.
我们报道了一种新型香豆素 - 肼共轭物3-{1-[(4,6 - 二甲基嘧啶 - 2 - 基) - 肼基] - 乙基} - 色烯 - 2 - 酮（3）的合成及其对锌的传感性能。化合物3可作为一种纯荧光锌传感器，其荧光强度增加并伴有明显的红移。荧光增强是由锌离子存在下通过顺反异构化过程形成络合物所致。通过成功的测试试剂盒实验证明了3在紫外光下检测水中锌的实际应用价值。
